Direct normal radiation
WebJul 31, 2024 · Direct Normal Irradiance (DNI) Direct normal irradiance represents the quantity of radiation received per unit area on a surface perpendicular (normal) to the sun. Consequently, a sun tracking pyrheliometer like the SHP1 measures DNI. Using a sun tracker like the SOLYS2 a pyrheliometer can track and point directly at the sun at all times. WebField: Direct Normal Radiation. This is the Direct Normal Radiation in Wh/m 2. (Amount of solar radiation in Wh/m 2 received directly from the solar disk on a surface perpendicular to the sun’s rays, during the number of minutes preceding the time indicated.) If the field is “missing ( 9999)” or invalid (<0), it is set to 0.
